Lead acid battery has been dominated the vehicle start battery market for more than one century. Lithium-ion battery is not good at cold-starting the engine and therefore cannot meet the requirements of starting batteries. Sodium-ion battery has excellent low-temperature discharge performance and can still meet the 10C pulse discharge requirements even at -28 degrees Celsius. In terms of CCA performance, sodium-ion battery is even more advantageous than lead acid battery.
Lead acid battery should strictly avoid over-discharge to prevent irreversible loss on capacity. Whilst Sodium-ion battery is not afraid of over-discharge and can be discharged to 0V, there will be no loss of capacity after recharging. Lead-acid battery usually needs to be charged every 3 months to keep the performance, while sodium-ion battery can extend the charging time to 12 months.
The abundance of sodium in the earth's crust is 2.3%, ranking sixth among all elements, and it is almost inexhaustible. Sodium is widely found on land and in the ocean in the form of salt and is easy to obtain. Compared with lead-acid battery, sodium-ion battery is 100% eco-friendly. Sodium-ion batteries do not contain any heavy metals and are 100% recyclable.
Why and how we designed the innovative and amazing
sodium-ion start-stop batteries?
Believe it, before you see it.
We believe sodium-ion batteries will change the market landscape for vehicle start batteries.
Sodium-ion Batteries 101
Sodium-ion battery is a secondary battery that mainly relies on the movement of sodium ions between the positive and negative electrodes to work. It has a similar working principle to lithium-ion batteries, and both are called "rocking chair" batteries.
The main components of sodium-ion batteries are positive electrode, negative electrode, separator, electrolyte and current collector, among which the structure and performance of the positive and negative electrode materials determine the sodium storage performance of the entire battery. The positive and negative electrodes are separated by a separator to prevent short circuits. The electrolyte infiltrates the positive and negative electrodes as a medium for ion flow, and the current collector plays the role of collecting and transmitting electrons. During charging, Na+ escapes from the positive electrode, passes through the separator and embeds into the negative electrode, so that the positive electrode is in a high potential sodium-poor state and the negative electrode is in a low potential sodium-rich state. The discharge process is the opposite. Na+ escapes from the negative electrode and passes through the separator and re-embeds into the positive electrode material, restoring the positive electrode to a sodium-rich state. In order to maintain charge balance, the same number of electrons are transferred through the external circuit during the charge and discharge process, and migrate between the positive and negative electrodes together with Na+, causing oxidation and reduction reactions at the positive and negative electrodes.
Sodium-ion Start-Stop Battery Advantages
Compared with lead acid starting batteries, sodium-ion start-stop batteries are a completely eco-friendly new battery chemistry. Sodium-ion start-stop batteries do not contain any heavy metals or precious metals and can be 100% recycled.
Sodium-ion start-stop battery is true deep cycle and can be discharged 100% depth of discharge or even gets to 0V without being damaged. When the engine stops to work, sodium-ion start-stop battery can independently power the on-board equipment for a long time, thereby effectively reducing carbon emissions.
Sodium-ion start-stop battery is integrated with intelligent battery management system, which achieves an emergency start function, thus ensuring your vehicle can be started smoothly at anytime, anywhere. It provides users with unprecedented driving protection.
Sodium-ion start-stop battery has a service life of up to 2,000 times and is completely maintenance-free. Its ultra-long service life can significantly reduce the user's installation, replacement and daily use costs.
